Experience Analysis on National Traditional Chinese Medicine MasterBan XiuwenTreatment of FemaleYin-Wei / 世界科学技术-中医药现代化

National traditional Chinese medicine (TCM) master professor Ban Xiuwen had rich experiences on treatment of gynecological diseases with unique insights on diagnosis and treatment for disorders of menstruation, leukorrhea, pregnancy and delivery. FemaleYin-Wei, which was a gynecological disorder, was recorded in the book ofHuang-Di Nei-Jing. However, due to different reasons, TCM study on femaleYin-Wei was far less than the study on male impotence. ProfessorBan Xiuwen had specific considerations for this disease on the book of Treatment of Miscellaneous Gynecological Diseases. In his understanding, femaleYin-Wei was due to four aspects, which were the innate deficiency, yang deficiency and coldness of the uterus; seven emotion damage, liver-qi soothing disorder; spleen-stomach deficiency,qi-blood deficiency; and phlegm-dampness stasis,qi stagnation. Through the analysis and study on case records of femaleYin-Wei treatment by national TCM master professorBan Xiuwen, this article briefly elaborated professorBan Xiuwen’s understandings on femaleYin-Wei treatment from etiology, pathogenesis, treatment according to syndrome differentiation, and clinical experiences. Two femaleYin-Wei cases treated by professorBan Xiuwen were given as examples in order to analyze the etiology, pathogenesis, treatment according to syndrome differentiation and treatment experiences in details. The therapeutic effects of both cases were obvious, which were also important study documents.

Determination of Moroxydine Residue in Tomatoes Using CdTe Quantum Dots as Fluorescence Probes / 分析化学

A novel method for the detection of moroxydine ( ABOB) residue in tomatoes was developed based on the enhancement of the fluorescence intensity of CdTe quantum dots( QDs) in the presence of ABOB. The factors influencing the performance of the QDs fluorescent probes were investigated, and the optimum conditions were determined:the concentration of mercaptoacidic acid ( TGA) capped-CdTe quantum dot was 1×10-4 mol/L, and the reaction time was 20 min at pH=5. 6. Under the optimum conditions, the relative fluorescence intensity increases linearly proportional to the ABOB concentration in the range of 1. 0×10-12-5. 0×10-10 mol/L with a limit of detection of 5. 2×10-13 mol/L, R=0. 9981, the recovery was 97%-106%, without obvious interference on the determinations of moroxydine from the common coexisting ions, antibiotics, and vitamins. The proposed method has been successfully applied in the detection of trace moroxydine hydrochloride residue in tomatoes.
